.IMPROVEMENT iN cRAcKER-MAci-IINES.

The Schedule referred tojn these Letters Patent mking part of -the sarde.

To all 'lq/toml 'it amy concer-nb Be it .known that I, WILLIAM GAlnns, of Jersey City, in the county .of Hudson and State of New Jersey, have `invented certain new and useful ImprorefV ments in Cracker-Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing forming part of this specification, .and in which-f vFigure 1 represents a' side elevation of a crackerxnaking machine constructed in V accordance with my invention;

Figure, a longitudinal vertical section ot the same;

Figure 3, a plan thereof, g 4 FigureV 4 is a sectional view in illustration'of the cutters and stamps in a different relative position to that shown 'for them in figs, l and '2.

Similar" letters of reference indicate corresponding parts. Y

, My invention relates to machines for making crackers from a web of dough in transit through vthe machine, and consists in various attachments or combinations and modes of operating certain parts or dcyices, whereby the cutters which press or cut out the crackers from the web and the stamps whichimpress the makers name or other distinguishing mark upon them are made to operate independently of each other; also, whereby the crackers arev detached from the web had the crackers detached, is 'delivered into a pan arranged to yreceive it; likewise whereby, and through the extension of tl Adelivery-apron 'inrear `ot` the machine, the pans used to contain the crackers while baking may be automatically fed so as to catch the crackers as they are detached from the web of dough.

Referring to the accompanying drawing- A represents the frame of the machine, which may be of any suitable construction.

B is the inclined table or board-down which the web of dough is passed to the feed-rollers C. C', the lower one, 0,0f which is,..driven and'has its requisite intermittent travel in a .forward direction, communicated to it by'a ratchet motion, deriving its action from a' pri'rnaryor driving-shaft, D

From these rollers the dough passeson to a traveling apron, E, arranged around rollers l; b,`tl1e one of which may be driven by belt from a pulley on the shaft of the'operating feed-roller (l,

Thisapron passes over a entting-b1ock',.li`, .on which and the remaining portion of theweb, after having the web of dough is iirst ont into crackers,and the.

latter subsequently stamped during each intermission Aot the feed.

By makingI the cutting operation vof the crackers separate and` distinct from the markingoperation.

plain cutters may be used, and there is less liability ofthe doughsticking to the cutters, anda likeadvantage accrues tothe separate stamping of the crackers.

The cutters and stamps may be variously constructed and arranged to thus operateindependently of each other, but the following arrangement and operation are' preferred.

G G are theA cutters, arranged side by side, and at tached to a` block, H, which is free to turner swivel in end slides I, that are fitted to travel up and down slotted guides J, arranged at right angles to the apron E. rIhese lslides I are moved up and down to elTect the operation of the cutters G on the dough by means ofeccentrics c on thedrivinglshaft D, or by any other suitable means.

y Attached to the cutter-carrying block His a pecnliarly-shaped slotted guide,'K, through which passes a fixed rod, L. The slot in this guide is of such shape that it directs the cutters G in av straight line when coming down upon or entering the-doughl and when leaving it,but so that, after the cutters are clear of the dough and while they perform the greater part of their up-stroke, they h`ave a swinging action or are thrown .back out ot' the way to make room for the stamps M to come into operation on the crackers just previously cut in the web, as represented in fig. 4.

The stamps M thus operating independently of the cutters, it is. also preferred'to give a swinging action to makeax-'ailablc the room temporarily afforded by the swinging action oi' the cutters, by attaching them,

or rather the bar N which -carries them, to bowed arms d, from a front cross `rocking-shaft, c, that derives its movement from the driving-shaft D by an" eccentric, f, rodg, and crank h.

'lhe relative movements of the stamps and cutters arc'so arranged that, as the cutters. ascend and are swungv out ot' the way, as hereinbefore described, the stamps are swung forward and down on the crackers, and as the cutters descend the stamps are thrown up and back again.

The web, with the crackers thus cut and stamped in it, next passes, by or during its intermittent feed,

from olio the apron E,'onto an inclined shelf or sup` port, i, from whence it passes toa stripping-roller, I, that has an intermittent motion communicated to it` by belt or otherwise, in direction of the arrow ft, and that serves to detach the crackers by the bend or run ot' the web, which is thus stripped up and partly round or-cver said roller, and under and over a free roller or guide, Q, from whence thescrap or cut web passes into a pan, R, for future use, said pan ,being emptied as required from time to time by upsetting it, for which purpose it and the roller Q are carried by side or swinging arms K, hung on fulcruins, as at m. lhe crackers, as cut and stamped, may-be delivered, as heretofore, direct onto an endless apron, S,

fitta i which, in traveling, carries off the crackers for after collection to be baked; but I prefer to extend this delivery-apron scas to project not only in front, but like- YWhat is Vhere claimed, and desired to be secured by.Y Y

1. The combination, 1n a cracker-machine, of the independent cutters G and stamps M, for successive operation on the web of dough, substantially as specified. Y

2. The combination, with theintermittently-rotating feed-rollers C C apron E, of 4the independently-operating cutters G and stamps M, essentially as herein set forth.

3.' The combination of the pivoted block H, which `carries the cutters, the slides I, and guides J, by which said block is directed in its upfandfdown movementand intermittently -travelingand the slotted guide K, with its -rod L, for effecting the swing of the cutters, essentiallyY as shown and described.

4. rlhe stamps M, having a swinging action, as dcscribcd, in combination with the independent cutters G, arranged to have a swinging action in rear or t0 one side of `the stamps, substantially as specified. 5. The combination of the stripping-roller P andthe scrapdelivery guide or roller Q, with the endlessftrav- 'eling aprons E and S, essentially as and for the pnrpose herein set forth.n

(i. rlhe scrap-pan R, in combination with the stripping-'roller P and the guide or roller Q, substantially as specified.

7. lhe scrap-pan It, arranged to swing or tilt as described, in combination with the roller or guide Q' and the stripping-roller P, essentially as specified.
